Comment 6 for bug 1852106

Added Nova to the bug. Quickest fix will be to modify the Nova non_inheritable_image_properties setting so that the problematic metadata are not inherited. Operators can make such a change without upgrading.

Glance fix will take longer and require an upgrade. (I'm not saying we shouldn't do it, just that it would be good to fix a possible data loss bug as fast as possible.)
